Custom-made 12 Module 40CrNiMoA Steel Double Helical Gear Shaft
The double helical gear total face is made into two equal halves, both with the same helix angle but with opposite hands.
The axial thrusts are opposite one another, the forces are contained in the gear and not transmitted to the bearing.
Double helical gear forms can balances the inherent thrust forces.
High loading capability and steady transmission are advantaged.
Double helical gears have been widely used for power transmission in gas turbine, generators, prime mover, pump,
fan, and compressor in marine ships and construction machine.
